I'm on the point of buying a bigger torch than the Proxxon minitorch I've been using up to now.
This one from Hamilton Gas looks like a good deal.
I've got a few questions I can't answer. If anyone can help with any I'd be grateful.
Firstly, would it be sensible for me to get an additional and bigger burner with this at the same time, such as the 3938, 3939, 3940, or will the burner supplied (the 8842 needle flame) be adequate for most purposes?
Also, I see quite a few people say they use the Bent Neck Tube (code 3511, I think). Could anyone tell me what advantage that gives over the standard set-up? Does it make the torch a bit easier to use in confined spaces or something?
I know the torch takes its oxygen from the air via a hole in the burner but there is no way of regulating the air flow, so the flame is always an oxidising flame, never a bushy one. I take it you just hold the torch further away from the workpiece if you want a gentler, bushier flame? Dennis mentioned he'd made a clip that he could slide across the airhole to regulate air intake. Is this as straightforward as it sounds, Dennis, i.e. just a case of making a snug-fitting open ring of brass or copper, preferably with some "wings" on the end so you can get hold of it easily to slide it back and to?
The last thing I can't find an answer to is do I have to get the biggish propane tanks (on a contract) from the outset or can I make do initially with the sort of
small propane tanks sold for plumbing at places like Toolstation? I suppose the crucial question is whether the fitting on the end of the tank is compatible with the Sievert hose.
Lastly, I'd be just as happy to buy an Orca, which I see some members have been happy with, but I'm unsure what items I'd need to buy in order to use this out of the box. Any help here would be appreciated.
Many thanks!
Mark.
